I look for three things in guidebooks. 1. Advice that won't get me lost. 2. Information on stuff I didn't know about before. 3. A sign of wit or humor. All of these matter, and I'm happy to say they're all abundantly presented in this book. Compared to a lot of the regional mt. biking books, this one is superior. The trail directions are clear, the histories & backgrounds are enlightening, and best of all, it's not boring or geeky. The maps are good too; unlike other books, they have a new map for each new route, instead of cramming three routes onto one dinky page. I also get the feeling that these authors worked a little harder than a lot of guidebook writers, who seem to hit one area then try to milk four rides out of one trail. In contrast, this book seems to cover a vast area with a lot more discrimination. The rides I've done so far have been fun and easy to follow. What more can you ask?
